    • Bipolar Plates for PEM Systems 

      Lædre, Sigrid (Doctoral thesis at NTNU;2016:247, Doctoral thesis, 2016)
      Summary of thesis: The Bipolar Plate (BPP) is an important component in both Proton Exchange Membrane Fuel Cells (PEMFCs) and Proton Exchange Membrane Water Electrolyzers (PEMWEs). Bipolar plate material and processing ...

    • Carbon-polymer composite coatings for PEM fuel cell bipolar plates 

      Husby, Hans; Kongstein, Ole Edvard; Ødegård, Anders; Seland, Frode (Journal article; Peer reviewed, 2014)
      A carbon-polymer composite coating on stainless steel 316L substrates was investigated for the use as bipolar plate material for polymer electrolyte membrane fuel cells. The coating consisted of 45 vol% graphite, 5 vol% ...

    • Coating for Metal Bipolar Plates in PEM Water Electrolysers 

      Krakhella, Kjersti Sandvik (Master thesis, 2015)
      To increase the efficiency of hydrogen as an energy storage medium, this project's goal is to lower the cost of Proton Exchange Membrane Water Electrolysers (PEMWE) by decreasing the cost of the most expensive component: ...

    • Conductive Coatings for Metal Bipolar Plates in Proton Exchange Membrane Water Electrolyzers 

      Olaussen, Tina (Master thesis, 2016)
      Due to the use of expensive materials, only 4 % of hydrogen production today is from water electrolysis. The most efficient low-temperature electrolyzer is the proton exchange membrane electrolyzer (PEMWE), where the bipolar ...

    • Economic and technical assessment of hydrogen and fuel cells opportunities in the Norwegian transport sector 

      Hubert, Karel Ludovic (Master thesis, 2015)
      Because of the environmental pressure concerning both global and local pollution new ways of using energy are under study. Given that the Norwegian transport sector is a significant contributor to those pollutions at the ...

    • Investigation of metallic bipolar plates for PEM fuel cells 

      Lædre, Sigrid (Master thesis, 2011)
      High cost and a short lifetime are the two main reasons why the PEM fuel cell is yet to be commercialized. The bipolar plate in a PEM fuel cell is alone responsible for about 45% of the cost and 85% of the total weight of ...

    • Materials for Proton Exchange Membrane water electrolyzer bipolar plates 

      Lædre, Sigrid; Kongstein, Ole Edvard; Ødegård, Anders; Karoliussen, Håvard; Seland, Frode (Journal article; Peer reviewed, 2017)
      Titanium based BiPolar Plates (BPPs) are commonly used in Proton Exchange Membrane Water Electrolyzers (PEMWEs) today as they can withstand the harsh operating conditions experienced inside an operating PEM water electrolyzer. ...

    • Measuring In Situ Interfacial Contact Resistance in a Proton Exchange Membrane Fuel Cell 

      Lædre, Sigrid; Kongstein, Ole Edvard; Ødegård, Anders; Seland, Frode; Karoliussen, Håvard (Journal article; Peer reviewed, 2019)
      Interfacial contact resistance (ICR) is one of the remaining hurdles for successful implementation of stainless steel bipolar plates in PEM fuel cells. We have developed a reliable method, using thin gold wires, to measure ...

    • Renewable hydrogen and synthetic fuels versus fossil fuels for trucking, shipping and aviation: A holistic cost model 

      Martin, Jonas; Neumann, Anne Franziska; Ødegård, Anders (Journal article; Peer reviewed, 2023)
      Potential carbon neutrality of the global trucking, shipping and aviation sectors by 2050 could be achieved by substituting fossil fuels with renewable hydrogen and synthetic fuels. To investigate the economic impact of ...

    • Soldering a gas diffusion layer to a stainless steel bipolar plate using metallic tin 

      McCay, Katie; Kongstein, Ole Edvard; Ødegård, Anders; Barnett, Alejandro; Seland, Frode (Journal article; Peer reviewed, 2018)
      A novel investigation to decrease the interfacial contact resistance of stainless steel bipolar plates was performed. A thin layer of Sn was electrodeposited onto a bipolar plate and subsequently joined with a gas diffusion ...

    • Ta-ITO Coated Titanium Bipolar Plates for Proton Exchange Membrane Water Electrolyzers 

      Lædre, Sigrid; Mendizabal, Lucia; Kongstein, Ole Edvard; Ødegård, Anders; Karoliussen, Håvard; Seland, Frode (Peer reviewed; Journal article, 2022)
      A novel bi-layer coating composed of a tantalum base layer with an Indium Tin Oxide (ITO) top layer was applied to titanium substrates. Samples were polarized ex situ in a parameter study, where the pH, potential and ...
